Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a method for CNC machining and prefabricated installation of complex metal antique-style buildings. Background Technology

[0002] With the rapid development of the social economy and the continuous improvement of people's living standards, tourism consumption has become an important part of the public's cultural life. In this process, the increasing cultural confidence has revitalized traditional architectural styles, and Chinese-style architectural scenic spots have gradually become a popular choice in the tourism market.

[0003] Currently, traditional architectural styles are limited by material properties and craftsmanship, and lack complete and systematic construction methods. Conventional construction methods generally result in long construction cycles, making it difficult to meet the needs of contemporary architectural development. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for CNC machining and prefabricated installation of complex metal antique-style buildings, thereby solving the problem of long construction cycles in traditional-style buildings in the prior art.

[0005] To achieve the above objectives, this invention provides a method for CNC machining and prefabricated installation of complex metal antique-style buildings, comprising the following steps:

[0006] S1. Digital Modeling and Prefabrication Planning: Based on architectural drawings, a high-precision BIM model is established, and digital detailing, node optimization, and manufacturing feasibility analysis are performed to generate component processing data.

[0007] S2. CNC machining of metal components: Based on the component machining data, 3D printing-based mold making technology is used to process metal components in the style of ancient architecture through investment casting.

[0008] S3. On-site prefabricated construction: On the construction site, the installation benchmark is located by measuring and setting out lines, and the embedded parts, frame and metal components are installed in sequence, and the overall assembly is completed by welding.

[0009] S4. Surface treatment: Coloring and sealing the assembled metal building to achieve an antique visual effect.

[0010] By adopting this technical solution, based on BIM models, 3D printing technology is used to quickly produce all the necessary components for the antique architectural style in modules, and prefabricated construction technology is used for on-site assembly, forming a complete construction system from manufacturing to assembly, which greatly shortens the on-site construction time and solves the problem of long construction cycles in traditional architectural styles.

[0011] Furthermore, the 3D printing-based mold-making technology in step S2 specifically includes:

[0012] Import the BIM model into blocks into 3D printing equipment to create component prototypes;

[0013] Using the component sample as the master mold, a silicone mold is made;

[0014] A wax model is made by coating the inside of a silicone mold with a casting material.

[0015] A casting system is welded onto a wax mold, and a ceramic shell is formed through processes such as coating with refractory materials, dewaxing, and firing.

[0016] Molten metal is poured into a ceramic mold, and after cooling, sand removal, and cutting of the gate, a metal casting is obtained.

[0017] Metal castings are welded and polished to form the final metal components.

[0018] By adopting this technical solution, based on architectural design style and pattern, and using 3D printing to produce component prototypes, including silicone mold making, wax model making, ceramic shell making, metal casting, and welding and polishing of metal castings, a manufacturing system is formed to obtain metal components that meet design requirements. This system enables the acquisition of metal components of different types and styles, and ensures the accuracy of the obtained metal components.

[0019] Furthermore, the casting system mainly consists of a pouring cup, a sprue, a runner, and an ingate, which is a channel for injecting molten metal into the ceramic mold shell.

[0020] By adopting this technical solution, the pouring cup, sprue, runner, and ingate form a channel connecting the inside and outside of the ceramic mold shell, so as to ensure that the molten metal can be evenly injected into the interior of the ceramic mold shell.

[0021] Furthermore, the molten metal is an aluminum alloy.

[0022] By adopting this technical solution, the lightweight properties of aluminum alloys facilitate on-site assembly of the final metal components, thereby improving assembly efficiency; the high strength and corrosion resistance of aluminum alloys extend their service life, thus extending the service life of the finished building.

[0023] Furthermore, step S3, on-site prefabricated construction, specifically includes:

[0024] S3.1 Measurement and layout: High-precision measurement and layout shall be carried out in stages during the installation of embedded parts, frame installation and metal components to ensure the accuracy of installation position;

[0025] S3.2 Embedded component installation: Chemical anchors are used to fix the galvanized embedded plate to the building substrate;

[0026] S3.3, Frame Installation and Welding: Based on the embedded parts, the prefabricated frame is welded on site into an integral load-bearing structure;

[0027] S3.4 Installation and welding of metal components: Install the metal components onto the frame and weld them using a water cooling method.

[0028] By adopting this technical solution, the embedded parts rely on the building base to provide the bottom connection position to realize the installation of the skeleton, and the skeleton provides the installation position of the metal components as the basic support, so as to realize the installation of the metal components and form the building structure of the required building.

[0029] Furthermore, the measurement and layout in step S3.1 is carried out using three-dimensional spatial dot matrix measurement and positioning technology for construction layout and installation positioning.

[0030] By adopting this technical solution, the three-dimensional spatial matrix measurement and positioning technology can simplify complex three-dimensional spatial data, improve the efficiency of back-end calculation and on-site layout, and improve the accuracy of construction layout.

[0031] Furthermore, after step S3.3, a thin fire-retardant coating is applied to the frame and welded areas.

[0032] By adopting this technical solution, fire resistance can be further improved.

[0033] Furthermore, the water cooling method involves continuously cooling the area surrounding the weld during the welding process.

[0034] By adopting this technical solution, welding heat energy is prevented from spreading, thereby reducing deformation.

[0035] Furthermore, the coloring in step S4 involves using chemical or physical methods to generate an oxide film or coating with a desired color on the metal surface.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. Based on the BIM model, 3D printing technology is used to quickly produce all the necessary components for the antique architectural style in modules, and prefabricated construction process is used for on-site assembly, forming a complete construction system from manufacturing to assembly, which greatly shortens the on-site construction time and solves the problem of long construction cycle of traditional style buildings.

[0038] 2. Based on architectural design styles and patterns, the system utilizes 3D printing to produce component prototypes, including silicone mold making, wax model making, ceramic shell making, metal casting, and welding and polishing of the metal castings. This forms a manufacturing system that obtains metal components that meet design requirements, enabling the acquisition of different types and styles of metal components while ensuring the accuracy of the obtained metal components.

[0047] Before proceeding to step S1, construction preparations should also be carried out, including the preparation of electricity, water and gas for construction, preparation of construction drawings, preparation of on-site tools and equipment, familiarization with construction drawings and related technical data, review of drawings, preparation of construction plans, technical briefing of drawings to prefabrication manufacturers and installation workers, determination of installation technical requirements and acceptance standards, and proposal of equipment and material entry plans based on project progress.

[0048] The 3D printing-based mold-making technology in step S2 specifically includes: importing the BIM model into 3D printing equipment in blocks to create component samples; using the component samples as master molds to create silicone molds; coating the silicone molds with casting material to create wax models; welding a gating system onto the wax models, and then coating them with refractory material, dewaxing, and firing them to form a ceramic shell; pouring molten metal into the ceramic shell through a gating system consisting of a pouring cup, sprue, runner, and ingate; obtaining a metal casting after cooling, sand removal, and gate cutting; and welding and polishing the metal casting to form the final metal component.

[0054] S3.3, Frame Installation and Welding: Based on the embedded parts, the prefabricated frame is welded on site into an integral load-bearing structure. The welds are full welds.
